Plastic stress-strain relations for combined tension and compression

Joseph Marin, H. A. B. Wiseman

The main purpose of this investigation was to determine the validity of the plasticity theories and the correctness of various assumptions made in these theories. For this purpose, plastic stress-strain relations for biaxial tension-compression principal stresses were determined for a 14S-T4 aluminum alloy. The combined tension and compression principal stresses were produced by subjecting a thin-walled tubular specimen to axial tension and torque.
